Four 50 g50\,\text{g} samples each absorb 420 J420\,\text{J} of heat. Their specific heat capacities are given below. • Aluminum: 0.90 J g−1 ∘ ⁣C−10.90\,\text{J}\,\text{g}^{-1}\,^{\circ}\!\text{C}^{-1} • Copper: 0.39 J g−1 ∘ ⁣C−10.39\,\text{J}\,\text{g}^{-1}\,^{\circ}\!\text{C}^{-1} • Ethanol: 2.4 J g−1 ∘ ⁣C−12.4\,\text{J}\,\text{g}^{-1}\,^{\circ}\!\text{C}^{-1} • Water: 4.2 J g−1 ∘ ⁣C−14.2\,\text{J}\,\text{g}^{-1}\,^{\circ}\!\text{C}^{-1} Which ranking correctly lists the substances from largest to smallest temperature increase after the heating? a) Copper >> Ethanol >> Aluminum >> Water b) Copper >> Aluminum >> Ethanol >> Water c) Water >> Ethanol >> Aluminum >> Copper d) Aluminum >> Copper >> Ethanol >> Water
